Good pair of pants to have for the winter.

October 28, 2021

Perfect fit and functiom

I especially like the absence of a thick elastic waistband.

August 22, 2021


The only product I've sent back for reimbursement via the Ironclad guarantee. Sadly, both pair I purchased wore through in the thighs. These are the most comfy and warmest base layers ever, so I was really bummed that there was no repairing the holes and that it happened on a second pair. I imagine that if you are wearing anything aside from a... Read More really smooth synthetic over top (think ski pants) and your thighs touch, there'll be holes, and it won't take long. Can't wait for Patagonia's awesome designers to get this sorted so I can invest in another pair.

Thank you so much for the feedback Johanna. We appreciate knowing where the problem areas are so we can adjust. We'll pass it along to the design team.

The perfect baselayer as long as your thighs don't touch

I bought my first pair from a local outdoor gear store in Alaska when they first came out. After 1 wear there was a hole in the inseam of the crotch and I was like oh that's a bummer, maybe it was just a fluke. The hole turned into the entire crotch getting blown out within a month and the pants had to be retired which is such a bummer because... Read More they are my favorite (and expensive). When they released the navy color I bought a second pair thinking the first was just a one off. Same thing happened. Worthless within a couple wears. For Xmas my mom got me a pair and I was over the moon because I had since gone through 2 pairs and desperately wanted them to work. Same thing happened. I own 3 of the air tops and the leggings even with the crotch worn out with holes were my staple for wearing under a layer for field work outside. If your thighs touch, these pants will not work for you. ever. I saw Patagonia respond to a review saying "there must have been some sort of abrasion happening at the seam" yes, Patagonia, it's called thighs touching. IF your thighs do not touch, these pants are the greatest. So warm. So soft. The perfect base layer. Sigh.

Warm and cuddly

I bought these for my upcoming JMT backpacking trip. Light weight, warm and cuddly for my sleeping bag at night after a long day of hiking. Perfect

June 16, 2021

Two months and going strong

I've been using this piece on the Pacific Crest Trail for the past two months and I still love it. I hike in it in cold temps, hang out in camp in it, sleep in it, then repeat the next day. Incredibly warm for its weight, yet still breaths well. I have gotten a couple holes in the crotch that I have easily repaired. Curious to see if it will h... Read Moreold up for a few more months!

Showing your underwear

Someone can clearly see your underwear when wearing these. Not okay!

Response from Patagonia
May 12, 2021

Hey Hedvig! We're so sorry you had this problem. These bottoms are built as a base layer, or long underwear if you will. They aren't expected to be used as an outer layer. You might like our [Centered Tights]( if you're looking for a nice legging.

April 22, 2021

So comfy, want to wear them all day

Just as comfortable as they look to be. Soft and breathable. Seams in all the right places. Looking forward to winter sports in these.

April 10, 2021

Warm enough... easily torn

Ive had these pants for only a few months and there is already a tear in the inseam... Im frustrated because the cost of these are high! I will see myself but beware these are delicate.

Response from Patagonia
April 12, 2021

Thanks for the feedback Megan! We're sorry to hear that they aren't holding up. They're covered by our Ironclad Guarantee so please reach out to our Customer Service team to set up a return.

March 27, 2021

Never want to take them off

Love these! Warm and cozy for both lounging and running in a snow storm. Looking forward to using these on my upcoming thru hike.

March 10, 2021

Super comfortable

These pants are amazing. Some how they manage to be warm, at at the same time feel like your wearing nothing.

March 7, 2021

Love them!

These are perfect lounge-around-the-house tights. Warm but breathable, wooly but not itchy. Im sure theyll be a great base layer, I just havent needed that yet. Nice relaxed waist that does not bind. Im 5 5 and about 122 lbs. Size small is perfect. Highly recommend!

March 3, 2021

Great fabric, construction and design need work

I am 5'9", 150lbs and generally a small/size 4-6. I love the fabric, these kept me super warm and toasty dry for snowboarding. Never felt the wind on the lift. They have a short inseam and fit more like a capri for me. I wish they offered a tall version. On the second day I wore them, the crotch ripped when I was pulling them on. The rep ... Read MoreI spoke to said this is an issue they are working to correct, and that I should treat them gently, which seems counterintuitive for base layers (they're not stockings). He also said I shouldn't pull them up too high, and that they should sit on the hip. I would honestly prefer a high waist fit for base layer pants, it feels more secure. I hope Patagonia updates these with reinforced seams, especially in the crotch, a longer inseam and a higher rise so they stay up.

February 21, 2021

Warm and a bit of unexpected stretch just after a few washes

These are very warm. The first few times I wore them as a base layer I was happy with them. However, after a few washes they started to ride up and are kinda more loose than I would like. Just based on cost alone, I expected these to hold up better. Id recommend looking elsewhere, especially if these will be in regular rotation in your winter wardr... Read Moreobe.

Warm layer for skiing

This layer is great for warmth and maneuverability when cross country skiing! Only issue is it does pull up from fuzz and hair because it is textured.

February 16, 2021

Perfect Fabric

The fabric is lightweight but very warm. Garment can be worn under fitted clothing easily. Only change I would like is a much shorter waistband. I am petite and the waistband is way too tall for my body.

Thank you for your excellent feedback on the rise, fit and fabric of these Capilene Air Bottoms, Judith!

February 14, 2021

Best yet for Winter fun!

I bought these long underwear hoping for less than I got. WARM, COMFORTABLE, easy to add a layer on top for single digit mountain weather. So good I bought a second pair... So GREAT, I bought a pair for my outdoors sports daughter. SHE LOVES IT too.

February 13, 2021

What a great difference these make!

These are great for layering under pants or sweats. Unlike other "thermals" this actually kept me warm! Love them.

February 11, 2021

Three months in and still going strong~!

I'm not used to spending this much money on an under layer but I have zero regrets. Working in a cold room and a cooler often I was in need of something durable, not constraining and okay to be washed at least weekly. I've been wearing them more than not since I got them 3 months ago and was worried about how they would hold up given some... Read More of the reviews I read but I sleep with them and move around a lot and haven't noticed any deforming or tears. The length is great and I will definitely be getting more merino wool material.

Great ski base layer

Super thin, stretchy fabric. Kept me perfectly warm on many ski trips!

February 2, 2021

Best Base Layer I've Ever Worn

I was hesitant to purchase these because of the price. Since the description and reviews described exactly what I wanted, I gave them a try. My primary use is warmth with a nice stylish look under skirts and dresses. I'm sure they will also be great under pants when I do some cold weather hikes. They look great, the few seams they have are act... Read Moreually difficult to find, they air dry quickly, they are extremely comfortable and warm, and the fit is perfect for me. I am 5'0" 113 lbs. and I purchased an XXS. I recall someone describing them as a sweater for your legs and I completely agree. After multiple wears, I am starting to notice some pilling on the thighs where my skirt rubs with movement. I think that's to be expected for this material and an easy fix. If they came in grey or brown, I would buy another pair.

January 25, 2021


Purchased the air bottoms for my wife. She absolutely loves them and has indicated that they are light weight and extremely soft and comfortable. She wore them out today for a 3 mile walk in 20 degree temperatures with a windchill making the temperature around 12 degrees. She is suggesting I purchase a pair of mens for myself.

January 24, 2021

Very comfortable

These are the best light long underwear I have had from Patagonia. Had many over the years too. Go great under all their pants. Warm but not stuffy feeling. Good wicking. Wear around house after an outdoor day.

December 24, 2020


I would not usually spend this much on base layer, but I did because hooray they do NOT have a seam in that place where I do not want a seam! Most base layers and tights seem to have a seam there. You know where. Thank you for finally offering a base layer without "that" seam!

December 22, 2020

Great Fit

This is the second pair of Air Bottoms I've purchased. I wear a pair everyday in the winter. They fit like a sweater around my waist. No painful waist band! Very warm and comfortable.

December 15, 2020

Shockingly Durable

I rolled my ankle and took a tumble on an asphalt trail last weekend while I was wearing these Capilene air bottoms. When I removed the pants to check my knee, I was surprised to see that my knee was so torn up and bloody because the pants had not sustained any damage at all. While these pants will not protect your skin (I never thought they would)... Read More, they are insanely durable (or maybe this was just a fluke incident?).

November 27, 2020

Definitely super cozy but pilling after one wash

When I put these on I felt love - seriously. Super cozy and kept me warm in wintry Yosemite recently. But, when I got home and washed them on gentle - and hung dry - they're pilling all up and down the sides of the legs : (

Response from Patagonia
December 23, 2020

Thanks for your feedback. Pilling is bound to happen on garments like this that encounter friction. Check out our [repairs videos]( on how to take care of that!

November 20, 2020

Super warm

I got these for MN winter and they were so warm layered under my yoga pants. The material is unique knit- I probably Should have sized down.

November 19, 2020

Warm and comfy

Wished I could wear these all day long. So comfortable! Great fit, awesome look and very warm worn under hiking or running pants. Also wonderful to wear by themselves around the house on a cold morning.

November 11, 2020

Warm and lightweight-- but pills

Very warm and lightweight. I am 5'6" 128 lbs and usually wear small or sometimes medium bottoms. The small fit perfectly. I have used it backpacking and bikepacking and they work great. When I first got them as a christmas present and I was living in my van in the winter (very cold) so I wore these to sleep in every night. They immediatel... Read Morey pilled and got lint allover them even though I had only slept in them and hadn't worn them for anything active yet. They still work great but have gotten a small hole in them. I think these issues might just be because they were the first edition. I later got an air capilene balaclava which has none of these issues at all. So I feel that the new base layers probably don't have these issues.

November 10, 2020

Sweater legs

Surprisingly fluffy and sweater like, these leggings are warm and comfy for running and hiking but I wouldn't wear them without a skirt over them when going to town.

October 30, 2020


They are so soft and warm. I wear them almost every day, early in the morning when the house is chilly. I ll wear them to walk and jog outside in the upcoming colder weather. Love, love love.

October 4, 2020

Breathable and warm, unfortunately not durable

Have been wearing these around the house with the intention to take them on an upcoming backpacking trip. The material is breathable and super warm, fit is true to size. In so many ways I'm happy with these leggings, however they wore a sizable hole in the crotch in less than 5 wears, no washes, with me just sitting in them around the house. T... Read Morehe seamless quality of this base layer is great, however I recommend finding some way to reinforce the areas of these leggings that may receive more day-to-day stress. For the price I paid for these, they unfortunately don't hold up.

Response from Patagonia
December 2, 2020

Hey there! Thanks for taking the time to write this review. While the coziness of this baselayer makes it tempting to wear on it's own, it's intended use is to be layered. Layering will help to extend the use of the garment. With that said, it should not be tearing with such limited use, please click [here]( to send it in for return. You could also consider looking at the Capilene Thermal Weight Bottoms for a baselayer option with a sturdier fabric.

September 23, 2020

Wow, wonderful material, but super big

I bought this baselayer for going home to the Arctic Circle. I'm 5'7" and almost 200lbs. By my measurements, I should be squarely in the XL category but when I put these on they fit less like a base layer and more like sweatpants. Rather than being skintight and good for wearing under jeans, there was actual loose fabric bagging and ... Read Moresagging behind my knees! Yes the material is super stretchy but this is without even the stretch being activated! I am ordering two sizes down to make up for this weird fit because I was SO impressed with the seamless soft knit material. As a Lapplander I have owned a LOT of base layers and these seem spectacular. I really hope they're opaque in a Medium despite my 44" hips and 34" waist, because I will wear them exclusively underneath skirts, jeans, and everything else if so!

August 8, 2020

Very cozy but...

These are 100% see through. I'm keeping them anyway bc they are super comfortable. A little loose but I am on the edge of a small and medium so I went with M to be safe, should have got a small. But if you hold these up to your eyes you can see through them very clearly. Just wear black underwear with them

July 20, 2020

Not designed for activity

Im currently hiking the John Muir trail and purchased the Air bottoms and top to wear to sleep. With minimal movement the pants have begun to rip at the side hip by night 4.

Doesn't hold up

I wear these bottoms primarily under my dry suit while kayaking and hanging out at camp/ sleep in on cold nights so they are hardly every exposed alone. However, they have formed a quarter size hole on the butt somehow. This has happened to me before with wool baselayers which is why I paid for these. I thought since they were a mixture of wool and... Read More polyester they would hold up better. I hope I can get them repaired because they are cozy and warm.

April 5, 2020

Thanks for your feedback, Kelli! While the Capilene Air Bottoms aren't exposed to the elements, it sounds like there may be some abrasion occurring between them and the boat, perhaps. Please [reach out]( to us so that we can help you [return]( them to our main service center for merchandise credit or a refund. We'll be happy to make some other product recommendations as well!

Best Patagonia Piece I Own

This is my all time favorite piece that I own from Patagonia. It is so versatile, warm but breathable, and soft. I wear these under my waders, ski pants, and jeans when its extremely cold. The waist comes up to the belly button which is helpful for layering. They are thin enough that you can get another tight layer on over them if need be. Im never... Read More too hot in these and always warm. These are a must have!! Best baselayer on the market to date.

Scratchy, Not made to last

I used these mainly to sleep in at night during a month long backpacking trip where I'd be at high elevation for most of the time. While they did keep me warm, they were uncomfortable to wear. I didn't like the feeling of them next to my skin. They were scratchy feeling and I dreaded putting them on each night. I had really bug bitten leg... Read Mores and the leggings just irritated them even worse. They also started to fall apart on the first week of my month long trip. There was a hole in the crotch and two holes on each side where the waist met the leg (likely from pulling them on). After washing them once, they were pilled and funky looking -definitely an under layer only. I did end up returning them, but I would not purchase these Capilene® Air Bottoms again, even though they're super lightweight.

Response from Patagonia
February 4, 2020

Hi Kate! Thank you for your review, and we're sorry to hear the Capilene Air Bottoms didn't work out for you. You might have some better luck with our [W's Thermal Weight Bottoms](, as this style does not feature any merino wool. They also have a taller waistband which promotes a more articulated, comfortable fit. Please feel free to [contact]( us if we can offer any additional guidance on the best kit for your needs. Cheers!

Warmest, Warm Pants

I got these pants before heading to Southern Utah for a winter adventure (low temps were -15 windchill - real life). We snowshoed, hiked the narrows, and hiked all over Zion, Bryce, and Grand Staircase-Escalante, and these pants were absolutely perfect. I was so warm, but not too warm. They never got funky after wearing them for many days in a row.... Read More They're soft af too! Thank you!

Warm and toasty!

Been teaching skiing for 25 years. These are the warmest and lightest thermals I've ever worn. It's been 12 degrees with wind and I'm comfy!

December 18, 2019

Best base layer ever

I love the Capilene line of base layers. They are lightweight and so very comfortable, yet are also very warm and cozy. The bottoms fit comfortably under jeans, yoga pants, hiking pants, because they are thin and not bulky. They also are not tight or binding. I bought another pair for my daughter for Christmas.

W;s Capilene Air bottoms

Love them, nice and warm but not woo warm, soft too!

December 12, 2019

had to order a smaller

had to order a smaller size than I expected, they needed to be tight against my skin so I ordered the size xs. they fit great except that my legs are too long. I am 5'8" and about 130lbs to give the idea. patagonia needs to work on more consistent sizing I think, and include the long-legged slender gals!

December 3, 2019

Toasty and Comfy

These are the warmest, coziest base layer under snow pants or jeans and great solo for running or just hanging out in a coolish house.

November 30, 2019

Love it!!!

It’s so light and warm, so excited to wear’em to my next trip to Patagonia in couple of weeks.

November 29, 2019

Nice n warm

They’re really good leggings and super warm, I will say I sized down like all the reviews said to do and got an XS and they were still big on me (I’m usually a small). I’m 5’2 and about 110 pounds and got xxs, just for reference!

I bought these for winter fishing when running out in the boat can be really cold but once you’re on the flat it warms up. Very comfortable in both situations, I.e., not hot when the boat stops and sun gets higher. I liked so much O ordered an extra pair.

Great base layer

Thumbs Up!

These capilene air bottoms are perfect for layering on a cold winter's day. I wear them for alpine touring, and I'll be sweating on the way up and they wick perfectly! On the way down, they stay cozy and warm! They also wash well and maintain their loft.

Super Warm and a must have for winter camping

These leggings are a game changer for colder blooded people for winter camping. Im 5'10 and 160 pounds and got a size large and they fit wonderfully on their own or over a pair of another leggings for extra warmth.

Tag fail

These long johns are really warm and comfy, but I gotta wonder why, after going to the trouble of making a seamless baselayer, they had to go and sew in not one, but TWO itchy labels.
